D
Euglena
E
Chlamydomonas
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
Green algae are known to form symbiotic relationships with a variety of organisms, including fungi, marine invertebrates, and some animals.Some hydra species, such as Hydra viridissima, have a symbiotic relationship with green algae. This symbiosis is characterized by the algae living within the hydra's endodermal cells, giving the hydra its characteristic green colour.

Solution
An association between two organisms in which both benefit is called
A
parasitism
B
commensalism
C
symbiosis
D
Predation
E
competition
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
An association between two organisms in which both benefit is a specific form of symbiosis. While the term mutualism is the most precise biological name for a relationship where both partners benefit, it is not provided as an independent option in this list. In many biological contexts and examinations, symbiosis is used as the general classification for these close, long-term interactions where at least one (and often both) organisms benefit.
